Remarks

The HttpBrowserCapabilitiesBase class is an abstract class that contains the same members as the HttpBrowserCapabilities class. The HttpBrowserCapabilitiesBase class enables you to create derived classes that are like the HttpBrowserCapabilities class, but that you can customize and that work outside the ASP.NET pipeline. When you perform unit testing, you typically use a derived class to implement members with customized behavior that fulfills the scenario you are testing.

The HttpBrowserCapabilitiesWrapper class derives from the HttpBrowserCapabilitiesBase class. The HttpBrowserCapabilitiesWrapper class serves as a wrapper for the HttpBrowserCapabilities class. At run time, you typically use an instance of the HttpBrowserCapabilitiesWrapper class to call members of the HttpBrowserCapabilities object.

Constructors
